Abstract:

In order to endow visual surveillance system with the ability of detecting and tracking moving objects, an intelligent visual surveillance device was developed utilizing davinci technology. The hardware was implemented using the dual-core chip TMS320DM6446 as the core processor and the software was designed under davinci software framework. The proposed moving objects detecting and tracking algorithm adopts background subtraction and edge detection techniques to segment the moving objects. Then, a features-matching method is proposed to find the temporal correspondences of segmented objects between successive frames. Test results show that, this device meets real-time video encoding requirement, detects and tracks moving objects effectively, and can record trajectories.

Key words: intelligent visual surveillance, davinci, moving object tracking
